Description

Technical Field

[0001] This utility model relates to the field of shaft assembly technology, and in particular to a shaft assembly device. Background Technology

[0002] In the field of automation, especially on transmission assembly lines, the assembly and meshing of the various shaft systems and differentials of the transmission has always been one of the most structurally complex workstations on the entire line. During the assembly process, the first gear shaft needs to be fixed and the second gear shaft needs to be moved to mesh with the first gear shaft. However, during the assembly process, the tips of the gear teeth may collide with each other, making it impossible to push the second gear shaft into place. If it continues to be pushed, it may cause excessive collision, damage the gear, and ultimately cause gear damage. Therefore, it is necessary to manually align the second gear shaft and the first gear shaft before assembly. However, manual alignment takes a long time and requires extremely high skills from the assembly personnel.

[0003] Therefore, there is an urgent need for a shaft assembly device to solve the above-mentioned technical problems. Utility Model Content

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0038] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0041] To address the problem of gear tooth tips colliding with each other during gear shaft assembly in the prior art, this embodiment provides a shaft assembly device that can detect the tooth tip of one of two different gear shafts and the tooth root of the other, ensuring that the tooth root and tooth tip mesh directly during assembly and preventing collisions between the two gear shafts during the assembly process.

[0042] like Figure 1 As shown, the shaft assembly device includes a support platform 1, a first support mechanism, a second support mechanism, and a first detection unit 4.

[0043] The first detection unit 4, the first support mechanism, and the second support mechanism are all equipped with support platforms 1. The first support mechanism includes a first support component 2, which supports the first gear shaft 100. The second support mechanism includes a second support component 3, which supports the second gear shaft 200. One of the first support component 2 and the second support component 3 can move relative to the other. The first detection unit 4 is used to detect the tooth tip of one of the first gear shaft 100 and the tooth root of the other.

[0044] The shaft assembly device provided in this embodiment uses a first detection unit 4 to detect the tooth tip of one gear shaft 100 and the tooth root of the other gear shaft 200. Only after the first detection unit 4 detects the tooth tip of one gear shaft 100 and the tooth root of the other gear shaft 200 can the second support component 3 and the first support component 2 be moved closer to each other, so that the tooth tip of the first gear shaft 100 and the tooth root of the second gear shaft 200 or the tooth root of the first gear shaft 100 and the tooth tip of the second gear shaft 200 mesh. This avoids collision between the tooth tip and the tooth root during assembly, prevents gear damage, improves NVH pass rate, and reduces rework costs.

[0045] It should be noted that the tooth base mentioned in this application refers to the tooth root.

[0046] In some embodiments, such as Figure 2 As shown, the first detection unit 4 is at least disposed between the first support assembly 2 and the second support assembly 3. Along the axial direction of the first support assembly 2, the projection points of the mounting point of the first detection unit 4 on the top surface of the support platform 1, the projection points of the central axis of the first support assembly 2 on the top surface of the support platform 1, and the projection points of the central axis of the second support assembly 3 on the top surface of the support platform 1 are all on the same straight line. By defining the position of the first detection unit 4, the first detection unit 4 can accurately obtain information on the tooth tip and tooth root of the first gear shaft 100 and the second gear shaft 200, avoiding damage caused by impact during the assembly of gears from two different gear shafts. In addition, it can improve assembly efficiency and reduce rework costs.

[0047] For example, the first detection unit 4 includes a first distance sensor 41 and a second distance sensor 42. The first distance sensor 41 is used to detect the distance between the first distance sensor 41 and the gear to be meshed on the first gear shaft 100, and the second distance sensor 42 is used to detect the distance between the second distance sensor 42 and the gear to be meshed on the second gear shaft 200. After the first distance sensor 41 and the second distance sensor 42 obtain the corresponding distances, they are compared with a preset distance range to determine that neither the distance detected by the first distance sensor 41 nor the distance detected by the second distance sensor 42 is the tooth tip or tooth root of the corresponding gear shaft. This allows the movement of the second gear shaft 200 or the first gear shaft 100 to achieve the purpose of shaft system assembly. The preset distance range is obtained through calibration tests. Different shaft systems have different preset distance ranges. Specifically, the preset distance range refers to the distance range from the first distance sensor 41 to the tooth tip or tooth root of the gear to be meshed on the first gear shaft 100, and the distance range from the second distance sensor 42 to the tooth tip or tooth root of the gear to be meshed on the second gear shaft 200, when the gear to be meshed on the first gear shaft 100 and the gear to be meshed on the second gear shaft 200 are able to mesh without collision. It can be understood that the preset distance range includes a first preset distance range and a second preset distance range. The first distance sensor 41 and the second distance sensor 42... When the distance between the gear to be meshed on the first gear shaft 100 is greater than the first minimum distance within the first preset distance range and less than or equal to the first maximum distance, and when the distance between the second distance sensor 42 and the gear to be meshed on the second gear shaft 200 is greater than the second minimum distance within the second preset distance range and less than or equal to the second maximum distance, the purpose of assembling the shaft system can be achieved by moving the second gear shaft 200 or the first gear shaft 100. Otherwise, the distance is detected again after rotating the second gear shaft 200 or the first gear shaft 100 until the shaft system assembly can be achieved by moving the second gear shaft 200 or the first gear shaft 100.

[0048] If the detected distances are all at the tooth root or tooth tip of the corresponding gear shaft, then the first gear shaft 100 and / or the second gear shaft 200 need to be rotated, and then detected again by the first detection unit 4, until the distances are no longer at the tooth tip or tooth root of the corresponding gear shaft, ensuring that the gears corresponding to the first gear shaft 100 and the second gear shaft 200 can mesh with each other. Normally, it is sufficient to rotate the first gear shaft 100 or adapt the first gear shaft 100 to the second gear shaft 200. Of course, in other embodiments, the positions of the first gear shaft 100 and the second gear shaft 200 can be adjusted simultaneously to ensure that no collision occurs when the first gear shaft 100 and the second gear shaft 200 mesh. Ideally, the distance detected by the first distance sensor 41 is the distance to the root of the tooth of the first gear shaft 100, and the distance detected by the second distance sensor 42 is the distance to the tip of the tooth of the second gear shaft 200, or the distance detected by the first distance sensor 41 is the distance to the tip of the tooth of the first gear shaft 100, and the distance detected by the second distance sensor 42 is the distance to the root of the tooth of the second gear shaft 200.

[0049] In some other embodiments, the first detection unit 4 includes an image acquisition unit used to obtain the state of the meshing point between the first gear shaft 100 and the second gear shaft 200. For example, the image acquisition unit includes a vision camera. After the vision camera captures an image of the meshing point of the first gear shaft 100 and the second gear shaft 200, it compares and analyzes the image with a preset image to determine whether the first gear shaft 100 and the second gear shaft 200 are suitable for assembly and meshing. For example, the comparison analysis obtains the positions of the tooth root and tooth tip of the meshing gears. The image acquisition unit can determine that the tooth tips and tooth roots of the two different gear shafts are arranged opposite each other, thus avoiding collisions during assembly due to tooth tips or tooth roots facing each other.

[0050] like Figure 3 , Figures 5 to 7 As shown, the first support assembly 2 includes a support structure 21 and a tensioning structure 22. The support structure 21 supports the first gear shaft 100. The tensioning structure 22 is partially located within the support structure 21 and can slide along the axial direction of the support structure 21. The tensioning structure 22 is used to tension and fix the first gear shaft 100. The tensioning structure 22 extends into the first gear shaft 100 and presses against the inner wall of the first gear shaft 100 to tension the first gear shaft 100, thereby achieving the purpose of tensioning and fixing. The support structure 21 and the tensioning structure 22 cooperate to support and fix the first gear shaft 100. In addition, the tensioning structure 22 is partially located within the support structure 21, which saves space compared to setting the support structure 21 and the tensioning structure 22 separately.

[0051] The support structure 21 includes a support sleeve 211, and the tensioning structure 22 includes a first driving member 221, a pull rod 222, and a tensioning member 223. The pull rod 222 passes through the support sleeve 211 and its two ends are located outside the support sleeve 211. The first driving member 221 is located at the bottom of the support sleeve 211 and is connected to the first end of the pull rod 222. The tensioning member 223 is located above the support sleeve 211 and is connected to the second end of the pull rod 222.

[0052] The tensioning component 223 includes a tension sleeve and a tension rod. The tension rod has a working part and a connecting part. The connecting part passes through the tension sleeve and is fixedly connected to the pull rod 222. The working part is a component whose diameter gradually increases from both ends to the middle. The bottom of the tension sleeve abuts against the end face of the support sleeve 211 to be limited. For example, the tension sleeve can be multiple elastic claws that are axially bound together by elastic elements. The inner wall of the elastic claws gradually increases in thickness from top to bottom. After the tension rod is pulled into the tension sleeve, the elastic claws are squeezed open by the working part of the tension rod. After the elastic claws are opened, they abut against the inner wall of the first gear shaft 100, thereby achieving the purpose of tensioning.

[0053] The specific structure and working principle of the tensioner 223 are similar to those of the tensioner, so they will not be described in detail in this embodiment.

[0054] Combination Figures 6 to 8 As shown, an end bearing 300 is provided at the end of the first gear shaft 100. An annular protrusion 212 extends outward from the end of the support sleeve 211 facing the first gear shaft 100. The central axis of the annular protrusion 212 is collinear with the central axis of the support sleeve 211. The diameter of the annular protrusion 212 is smaller than the outer diameter of the inner ring of the end bearing 300 of the first gear shaft 100, and larger than the inner diameter of the inner ring of the end bearing 300. When the tensioning structure 22 operates, it will axially pull the first gear shaft 100, which may damage the cage of the end bearing 300, affecting the overall rotational accuracy and lifespan of the end bearing 300. Therefore, the annular protrusion 212 is provided to directly support the inner ring of the end bearing 300, preventing cage damage and ensuring the overall rotational accuracy and lifespan of the end bearing 300.

[0055] like Figure 3 As shown, the first support assembly 2 also includes a limiting cover 23. The limiting cover 23 is fixedly installed on the end of the support sleeve 211 facing away from the support platform 1, and the limiting cover 23 has an open receiving cavity. The end of the support sleeve 211 facing away from the support platform 1 extends into the limiting cover 23, and the central axis of the limiting cover 23 is collinear with the central axis of the support sleeve 211. The limiting cover 23 can prevent the position of the first gear shaft 100 from shifting from that of the support sleeve 211 when it rotates, thus avoiding affecting the subsequent tensioning and fixing. In addition, the setting of the limiting cover 23 can also pre-install and position the first gear shaft 100, so as to achieve the purpose of rapid installation.

[0056] In other embodiments, the support structure 21 includes a support column and a clamping part, the clamping part being fixedly connected to the support column, and the clamping part being used to clamp the outer peripheral wall of the second gear shaft 200. Specifically, the clamping part may be a pneumatic gripper.

[0057] like Figure 4 As shown, the first support mechanism further includes a rotating component 5, which is connected to the first support component 2 to allow the first support component 2 to rotate. For example, as... Figure 1 As shown, the rotating component 5 includes a rotating motor 51 and a reducer 52. The rotating motor 51 is a servo motor. The rotating motor 51 and the support sleeve 211 are connected by the reducer 52. The reducer 52 can reduce the rotation speed of the rotating motor 51 before transmitting it to the first support component 2. The reducer 52 can be a two-stage gear reducer.

[0058] In some other embodiments, such as Figure 5 As shown, the rotating assembly 5 includes a pulling cylinder 53, a rotating rack 54, and a rotating gear 55. The pulling cylinder 53 is fixed to the rotating rack 54, and the rotating gear 55 is fixedly connected to the first support assembly 2. The rotating rack 54 moves linearly under the action of the pushing and pulling cylinder 53, thereby driving the rotating gear 55 to rotate, so that the first support assembly 2 can rotate relative to the second support assembly 3.

[0059] It should be noted that when the first gear shaft 100 needs to be fixed, the rotating component 5 does not work, and when the first gear shaft 100 needs to be rotated, the tensioning structure 22 does not work.

[0060] In some embodiments, the rotating component 5 includes a rotating motor and a reducer. The rotating motor 51 is a servo motor. The rotating motor is connected to the support sleeve 211 through the reducer. The reducer can transmit the speed of the rotating motor 51 to the support sleeve 211. The reducer can be a two-stage gear reducer, so that the first gear shaft 100 can achieve the purpose of rotation adjustment.

[0061] Of course, in other embodiments, the rotating component 5 includes a rotating motor and a reducer. The rotating motor 51 is a servo motor. The rotating motor is connected to the first driving component 221 through the reducer. The reducer can reduce the rotational speed of the rotating motor before transmitting it to the first driving component 221. The reducer can be a two-stage gear reducer, so that the first gear shaft 100 can achieve both tensioning and rotation adjustment.

[0062] Since the installation of the rotating motor 51 increases the height of the first gear shaft 100, in order to assemble the first gear shaft 100 and the second gear shaft 200, please refer to [the relevant documentation / reference]. Figure 1The shaft assembly device also includes a support plate 10, which is arranged parallel to the support platform 1. The support plate 10 and the support platform 1 are fixedly connected by a support member 11, which is a columnar structure. The rotating motor 51 and the first driving member 221 are located between the support plate 10 and the support platform 1, and the rotating motor 51 and the first driving member 221 are fixed to the support platform 1. The second support assembly 3 is fixed to the support plate 10 to assemble the first gear shaft 100 and the second gear shaft 200.

[0063] In some embodiments, the second support assembly 3 includes a support rod, a support plate, and a limiting rod. The support rod is movable relative to the support platform 1. The support plate is fixed to the top of the support rod, and the limiting rod is fixed to the top of the support plate. The limiting rod can extend into the second gear shaft 200 to axially limit the second gear shaft 200.

[0064] In some embodiments, continue to refer to Figure 1 The second support mechanism also includes a moving component 6, which is connected to the second support component 3 to make the second support component 3 move, thereby ensuring that the second gear shaft 200 moves toward the first gear shaft 100 so that the gear to be meshed on the second gear shaft 200 and the gear to be meshed on the first gear shaft 100 can mesh.

[0065] like Figure 4 As shown, the moving component 6 includes a second driving member 61 and a pulling member 63. The pulling member 63 is connected to both the second driving member 61 and the second support component 3. The second driving member 61 drives the pulling member 63 to move linearly. The pulling member 63 provides a connection between the second driving member 61 and the second support component 3 to ensure that the second support component 3 can move under the drive of the second driving member 61.

[0066] The moving component 6 also includes a guide structure 62, which is connected to the second support component 3 to enable the second support component 3 to move linearly relative to the guide structure 62. The guide structure 62 provides guidance for the second support component 3. For example, the guide structure 62 includes a slide rail and a slider. The slide rail is fixed to the support platform 1, and the slider is slidably connected to the slide rail. The second support component 3 moves along the length of the slide rail, and the slider is fixedly connected to the second support component 3 to drive the second support component 3 to slide linearly relative to the support platform 1. Specifically, the guide structure 62 is fixedly connected to the support rod to realize the sliding and guiding of the support rod.

[0067] For example, the second driving component 61 is a cylinder, and the pulling component 63 includes a pulling rod. Of course, in other embodiments, the pulling component 63 can also be a pulling plate. The cylinder rod of the cylinder is fixedly connected to the pulling rod, so that the cylinder can drive the pulling rod to move linearly.

[0068] In some embodiments, the second drive member 61 includes an adjusting cylinder and a pressure reducing valve. The pressure reducing valve is connected to the adjusting cylinder to adjust the amount of gas entering the adjusting cylinder. The cylinder rod of the adjusting cylinder is fixedly connected to the pulling member 63. The pressure reducing valve ensures that the movement of the second gear shaft 200 is more stable as the second gear shaft 200 and the first gear shaft 100 approach each other.

[0069] In some other embodiments, the pulling member 63 includes a moving gear and a moving rack, and the second driving member 61 is a motor. The motor is connected to the moving gear to make the moving rack move linearly. The moving rack is connected to the second support assembly 3 to make the second support assembly 3 move linearly along the length direction of the rack. Optionally, the motor can be a servo motor, so that the rotation angle of the gear can be controlled, thereby precisely controlling the stroke of the rack.

[0070] like Figure 4 As shown, the number of movable components 6 is limited according to the number of second support components 3. The movable components 6 can be set on the top of the support platform 1 or in the space enclosed by the support platform 1.

[0071] The first gear shaft 100 can be the driving gear shaft, and the second gear shaft 200 can be the driven gear shaft. Of course, it is also possible that the first gear shaft 100 is the driven gear shaft and the second gear shaft 200 is the driving gear shaft.

[0072] It should be noted that when the second gear shaft 200 is the driven gear shaft, the number of the second support mechanism is not limited to one, but can be determined according to the number of second gear shafts 200 during the actual shaft system assembly. The number of the second support mechanism is the same as the number of second gear shafts 200. The number of second support components 3 is at least two. The second support components 3 are located around the first support component 2, and the positions of the second support components 3 and the first support component 2 are determined according to the shaft system to be assembled.

[0073] In some embodiments, continue to refer to Figure 1The shaft assembly device also includes a limiting mechanism 7. Each moving component 6 has two limiting mechanisms 7. The moving component 6 also includes a limiting member 64, which is fixedly connected to the second support component 3. The limiting member 64 is positioned between the two limiting mechanisms 7. The limiting mechanism 7 limits the travel of the limiting member 64, thereby limiting the travel of the pulling member 63. The limiting mechanism 7 includes a support member and a buffer damper. The pulling member 63 is located at one end of the second support component 3, and the pulling member 63 and the limiting member 64 are spaced apart. The buffer damper is fixed to the support member and located at both ends of the moving direction of the limiting member 64, thus limiting the linear travel of the limiting member 64 and preventing the second support component 3 from over-moving. Furthermore, it prevents excessive impact when the second gear shaft 200 approaches the first gear shaft 100, achieving safe limiting, and also prevents the second support component 3 from detaching from the guide structure 62. It should be noted that the dimensions of the limiting mechanism 7 can be determined according to the product dimensions.

[0074] In some embodiments, the shaft assembly device further includes a second detection unit 8, which is used to detect whether the first gear shaft 100 and the second gear shaft 200 are installed in place. For example, the second detection unit 8 is a proximity switch.

[0075] In some embodiments, the shaft assembly device further includes a handle 9, which is fixed to the second support component 3 and can be pushed and pulled to prevent the second support component 3 from being unable to move due to a malfunction of the moving component 6. The handle 9 can serve as an emergency measure.

[0076] The second gear shaft 200 includes a first-order second gear shaft and a second-order second gear shaft. Correspondingly, there are two second support components 3, which are used to support the first-order second gear shaft and the second-order second gear shaft, respectively. The working process of this shaft system assembly device is as follows:

[0077] 1. After the robot places the first gear shaft 100 on the first support component 2 and the first-order second gear shaft on the second support component 3, the tensioning structure 22 tensions the inner diameter of the first gear shaft 100 and then transmits a signal to the first detection unit 4 between the meshing point of the first gear shaft 100 and the first-order second gear shaft. If the meshing point of the two is misaligned, the first drive component precisely controls the rotation of the first gear shaft 100 to achieve adaptive adjustment of the meshing point.

[0078] 2. After the adaptive adjustment is completed, the various components of the second support mechanism cooperate with each other to bring the first-order second gear shaft closer to the first gear shaft 100, thus completing the meshing of the first-order gear shaft.

[0079] 3. After the first-order gear shaft is engaged, the above steps can be used to achieve the engagement of the second-order gear shaft; when the second-order gear shaft is engaged, the first-order second gear shaft rotates together with the first gear shaft 100.

[0080] 4. After the second gear shaft of the second order is engaged, the first gear shaft 100 drives the first-order second gear shaft and the second-order second gear shaft to rotate until they rotate to the original position of the robot arm. When the robot arm is in position, the tensioning structure 22 is released to release the first gear shaft 100.

[0081] 5. After the robotic arm leaves the gripper, the second support mechanism returns to its original position and performs steps 1-4 above.

[0082] The shaft assembly device provided in this embodiment is equipped with a sliding structure at the bottom. When the assembly fails, it can slide to the manual inspection area through the sliding structure. After the fault is eliminated through manual inspection in the manual inspection area, it can return to the original position for assembly.

[0083] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention.
